what is your EV charger grid limit?

[Greenmantle]

I'm thinking of upping my grid limit.
Using a Myenergi Zappi and the limit is currently 14kWh.
What is the general PH thoughts?

My thought is that I don't understand the question.

if you have a harvi module which monitors the current being drawn into the whole property you can set the zappi so that it will stop / reduce charge when the threshold is set.

my mains supply (single phase) has a 100A fuse so theoretically I can draw about 23KWH in 60 minutes but my zappi is set to stop charging when I go over 14KWH.

So your EV charger is set up to stop charging if your whole-home draw in any one-hour period ever goes above 14kWh? Why on earth would you want such a limit?

ETA: Or do you mean it throttles moment-by-moment to 14kW total grid draw? That would seem more... useful, since it would allow you to run the charger with a smaller main fuse without risk of blowing it. Still pointless if you have a 100amp main fuse though. We have no such limit in place as far as I know, not that I think we'd ever have noticed if we did!

I have friends who live in very rural places. They have iffy grid and have to be careful about how much is drawn at times as it trips some fuse in the grid and affects about half a dozen houses in the valley. But we are talking west coast Scotland....

Yeah capping the power would make some sense in some niche situations, if that's what the OP meant to say.
